CHECK FOR PlCKER-STlCKS.

SPECIFICATION forming part of Letters Patent No. 668,363, dated February 19, 1901.

Application filed August 8, 1900. Serial No. 26,208. (No model.)

4'0 all whmn it may concern:

Be it known that I, EDWIN TRAOHSLER, a citizen of the United States, residingin Paterson, in the countyof Passaic and State of New Jersey, have invented certain new and useful Improvements in Checks for Picker-Sticks; and I do hereby declare the following to be a full, clear, and exact description of the inven tion, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to looms, and it has reference particularly to that portion of a loom which constitutes its shuttle-actuating mechanism.

The ordinary shuttle-actuating mechanism of course includes as its principal elements a reciprocating picker, against which one end of the shuttle directly impinges, and a fulcrumed part, called a picker-stick, which is suitably actuated to impart sudden thrusts to the picker to thus throw the shuttle. I11 a box-loo1n, to the shuttle-actuating mechanism of which my invention is particularly applicable, where the shuttles as a series have to be occasionally shifted in order to bring into operative position a shuttle other than that last shot through the shed it becomes necessary to provide for a clearing of the picker from the point of the shuttle each time such shifting of the shuttles is effected, for

in time a slight recess becomes formed in the picker by the points of the shuttles which impinge against it with considerable force when returned to their boxes. At present this clearing of the picker from the point of the engaging shuttle is effected at the proper time by a strap projecting from a stationary par of the loom-frame and connected to the picker stick, which as it vibrates back and forth with the batten and passes the point of connection of said strap to the loom-frame is permitted to swing slightly outwardly under tension of the spring normally controlling it, and thus the picker is moved the required distance in order to clear the shuttle.

The object of my invention is to provide in place of this strap a simple and more durable attachment for looms which shall at the same time serve as a check to the pick er-stick as it recedes under tension of its spring and act to thereupon produce in said picker-stick the movement above mentioned as desirable in order to effect the clearing of the picker from the points of the shuttles.

My invention is fully illustrated in the .accompanying drawings, Wherein- Figure 1 is a rear view of the end portion of a loom provided with my attachment. Fig. 2 is a somewhat-enlarged view in elevation, showing said attachment secured to a portion of the loom-frame; and Figs. 3 and tare views of detail parts of the attachment.

In the accompanying drawings, a, designates one of the end uprights of the loom, in which is journaled a short rock-shaft b. 'On one end of said rock-shaft is sustained one of the lay-swords c of the loom, the other end of said rock-shaft being formed into a bracket (1, in which is fulcrumed the lower end of the picker-stick e, as at f, and in which is guided a rod g, through the medium of which some well-known mechanism is adapted to actuate the shuttle-boxes, (not shown,) which are arranged to reciprocate in an auxiliary frame 71, projecting from the lay-sword c.

To the lower end of the picker-stick is connected a spring 2', which is in turn connected to some stationary part and which normally acts to hold the picker-stick in the position in which it appears in Fig. 1. The pickerstick is adapted to be smartly actuated against the tension of its spring by an arm j, which is connected to it through the medium of a strap 76 and which is mounted on a squared shaft Z, which is journaled in suitable brackets m, projecting from the loom-frame.

The picker n, which is penetrated by, and thereby has a loose engagement with, the upper end of the picker-stick e in the usual manner, slides on a horizontal rod 0, suitably arranged in the auxiliary frame h, a slot p being formed in this frame opposite the rod, through which the picker projects so as to reach the shuttles.

q andr are simply stops niting the throw of the picker-stick.

My attachment is adapted to be secured, preferably, to some portion of the end upright a, which is approximately opposite the middle part of the picker-stick, as the horizontal I-bar sin the drawings. To said I-bar are secured, as by bolts 75, angle-i rons u, the adjacent faces of the free or projecting portions 2; of which are provided with grooves w.

as and y denote a pair of horizontal arms, of which the former is slightly longer than the latter. Each of these arms has one end slightly offset, as at 2, said offset portion being adapted to fit into the groove win one of the angleirons. In order to secure each arm to its respective angle-iron, a bolt 1 is employed, the same penetrating an opening 2 in the arm and a slot 3 in the angle-iron. The free end of each arm is bifurcated horizontally, said arms being thus adapted to receive the ends of a buffer consisting of a plate 4, to the inner face of which is secured, as by small bolts 5, a pad or cushion 6, of leather, rubber, or other similar material. The buffer is secured in place by pins 7, penetrating its ends and the ends of the arms a: and y.

The action of the picker-stick as influenced by my attachment is as follows: When the shed is open and the picker-stick is actuated to throw a shuttle through the shed, said picker-stick leaves the pad or cushion 6 of the buffer, against which it is normally held by the spring t' at the end thereof adjacent the arm y. When the picker-stick returns, the batten now having been slightly advanced in the operation of beating up the filler just carried through the shed, it impinges against the pad or cushion of the buffer at about the point where said picker-stick is shown as engaging said pad or cushion in Fig. 2. Now as the batten continues to advance to complete the beating up operation, since the picker-stick contin ues in engagementwith the pad or cushion under tension of the spring 1;, and since the buffer of which said cushion forms a part is disposed obliquely with reference to the upright a of the loom-frame, the picker-stick assumes a slight outward movement, as will be manifest. This movement is imparted to the picker and is just enough to clear the same from the engaging shuttle, so that the sh Little-boxes may be operated unimpeded. The extent of this movement of course depends upon the positions of the arms w and y1l. 6., whether the one extends more or less outwardly from the loom-frame than the other. After the changing of the boxes has been effected, and when the batten returns, the picker-stick is forced back by the obliquely-set buffer until the picker again engages a shuttle.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is

1. In a loom, the combination, with a frame and with a vibratory support arranged therein, of a picker carried by said support and adapted to reciprocate therewith and also substantially transversely of the direction of movement thereof, a picker-stick fulcrumed in said support and operatively connected to said picker, said picker-stick being movable with the picker and also with the support, a buffer arranged in contacting proximity to said picker-stick and obliquely relatively to the direction of movement thereof with the support, elastic means normally forcing said picker-stick toward the buffer substantially stationarily, and supports engaging said buffer at each end and sustaining the same on the frame, substantially as described.

2. In a loom, the combination, with a frame and with a vibratory support arranged therein, of a picker carried by said support and adapted to reciprocate therewith and also substantially transversely of the direction of movement thereof, a picker-stick fulcrumed in said support and operatively connected to said picker, said picker-stick being movable with the picker and also with the support, a buffer arranged in contacting proximity to said picker-stick and obliquely relatively to v the direction of movement thereof with the support, elastic means normally forcing said picker-stick toward the buffer, and adjustable supports engaging said buffer at each end and sustaining the same on the frame, substantially as described.

3. In a loom, the combination, with a frame and with a vibratory support arranged therein, of a picker carried by saidsupport and adapted to reciprocate therewith and also substantially transversely of the direction of movement thereof, a picker-stick fulcrumed in said support and operatively connected to said picker, said picker-stick being movable with the picker and also with the support, a buffer arranged in contacting proximity to said picker-stick and obliquely relatively to the direction of movement thereof with the support, elastic means normally forcing said picker-stick toward the buffer, and adj ustable supports sustaining said buffer on the frame and pivotally engaging the same, the one at one end and the other at the other end thereof, substantially as described.

In testimony that I claim the foregoing I have hereunto setmy hand this 28th day of July, 1900.
